Who’d have thought we’d be happy to see an unassuming black box? Delphi and Verizon managed to whet our interest with their Vehicle Diagnostics kit and service at CES, and our curiosity is renewed now that the monitoring combo is available for drivers. The finished product costs a fairly steep $250 for the Delphi adapter, although it does deliver two years of free service and costs a contract-free $5 per month afterwards. Shelling out brings the promised remote troubleshooting and notifications, including alerts for any performance problems and warnings for any geofencing violations. If you’re willing to pair an Android or iOS phone with the kit over Bluetooth, you can also use the smart device in place of your keys — temporarily, we hope. Vehicle Diagnostics should work with most cars made from 1996 onward, but do some homework before any outlay: at least a few cars miss out on the full diagnostic suite, which might dampen dreams of a connected car utopia.
